DC Studios co-head James Gunn has shared a teaser photo of Milly Alcock as Kara Zor-El in Supergirl.

“Thrilled to see cameras roll at Warner Bros. Studios Leavesden on Supergirl, with Craig Gillespie at the helm and the phenomenal Milly Alcock as our Kara Zor-El,” Gunn shared on X. “Craig brings an incredible sensibility to this story, and Milly is every inch the unique #Supergirl envisioned by Tom King, Bilquis Evely & Ana Nogueira.”

The DC Studios movie is based on Tom King’s 2022 comic book series Supergirl: Woman of Tomorrow, which Bilquis Evely illustrated. Ana Nogueira adapted the comic book for the big screen.

In that comic, the villain is Krem of the Yellow Hill, who kills a young alien girl’s father. She draws Supergirl into the conflict. Knolle is a noble and honorable warrior who travels across the galaxy with Supergirl to hunt Krem for killing her father in cold blood.

Three Body Problem star Eve Ridley will play Ruthye Mary Knolle in the film, while Rust and Bone actor Matthias Schoenaerts plays Krem.
